DEVICE FOR WINDING SILK, COTTON, OR OTHER MATERIALS ON WIRE.

SPECIFICATION forming part of Letters Patent No. 767,267, dated August 9, 1904A..

Application filed November 14, 1901. Renewed June 8, 1904. Serial No. 211,670. (No model.)

To all whom, it 17mg/ concern.-

Be it known that I, CONRAD FELSING, Jr., manufacturer, a subject of the German Emperor, residing at4Kaulsdorferstrasse,Coepenick, near Berlin, Germany, have invented certain new and useful Improvements in Devices for I/Vinding Silk, Cotton, or other Materials on IVire; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in devices for winding or spinning silk, wool, cotton, or the likel on a central thread or a wire, either naked or insulated by acoating of india-rubber, gutta-percha, or other suitable material.

In my improved apparatus, which belongs to the class of spinning devices in which the central thread or wire is led through the longitudinal opening in the bobbin or spool carrying the exterior thread, the box or casing containing said bobbin or spool and rotating with the latter is provided with several contrivances by which the final result is improved. These contrivances, which are all disposed in such a manner that during the rotation of the box or casing all injurious inuences due to centrifugal force are avoided, consist, in the first place, of a peculiar automatic brake which under the influence of centripetal force retards the motion of the bobbin or spool, and thus controls the unwinding of the vexterior thread; secondly, of a smoother connected to said box or casing and resting on the interior surface of the thread or wire guide, said smoother being designed to equalize the exterior thread while the same is wound onto the central thread or wire, and, thirdly, of different parts connected to the box or casing and designed to guide the exterior thread in a safe manner, these parts consisting of metallic eyelets or loops and a vertical tube of suitable diameter.

' In the accompanying' drawings, forming a part of this specification, and in which similar numerals of reference indicate corresponding parts throughout the several views, Figure 1 is a front elevation of my improved spinning device; Fig. 2, a plan of the same; Fig. 3, al sectional elevation on the line A B of Fig. 2; Fig. 4, a sectional plan on the line C D of Fig. 3; Fig. 5, an elevation of the smoother resting against the thread or wire guide, the latter being shown in section; Fig. 6, a top view of the curved or loop-shaped spring acting as an automatic brake to retard the motion of the thread-bobbin, while Fig. 7 shows the brake-tube forming one of the essential parts of the automatic brake.

The cylindrical box or casing 1 of the apparatu-s is provided with a bottom part 2, carrying a hollow spindle 3, through the opening of which passes the central thread or wire. The hollow spindle 3 carries the brake-tube, composed of a hollow spindle 19, having a grooved brake-pulley 2O at its lower end, Figs. 3 and 7. The hollow spindle 19, which has a conical shape exteriorly, receives the usual paper tube 23, carrying the thread bobbin or spool 1l, Fig. 3.

To the exterior of the box or casing 1 is lixed the one extremity of a loop -shaped brake-spring 21, which passes in two places through the box or casing 1, Figs. 4 and 6, said spring 21 engaging into the groove of the pulley 2O of the brake-tube and embracing more than half of the circumference of said pulley 20. The exterior end of the brakespring 21 is provided with the eyelet 22, which serves as a knob or handle to press in the spring 21, so as to enlarge the diameter of the loop formed by said spring 21 sufficiently to disengage the pulley 2O of the brake-tube, and thus enable the removal of the latter.

The cover 4, embracing the upper part of the box or casing 1, is secured to the latter by means of a spring 5, provided with a pin 6, engaging into a corresponding hole 7 in the cover 4. In order to remove the cover 4, the spring 5 is pressed against the box or casing 1, so that the pin 6 is disengaged from the hole 7. The hollow spindle 3 passes through the cover 4. Further, on the top of the latter are provided a grooved guide-pulley 9 and the thread or Wire guide 8. Against the inner surface o f said thread or wire guide 8 rests the head part or block 24 of the smoother, said block 24 being supported by a spiral spring 25, fixed to a pin 26, carried by the bracket 27, Fig.

The box or casing 1 is held and rotated by mcans of the driving-pulley 13, suitably connected to the bottom 2 of the casing 1. Said driving-pulley 13 turns on the balls 14, inserted between the journals 15 and 16 of the hollow support 17 and the driving-pulley 13, respectively. The part 16 is screwed onto the cnd 13 of the support 17, which carries the whole device.

The thread 10, unwound from the bobbin or spool 11, passes through the vertical slit 12 of the box or casing' 1, th'en through the first eyelet or loop 23, the vertical tube 29, the second eyelet or loop 30, and over the grooved guide-pulley 9, so as to reach the central thread or wire passing' through the hollow spindle 3, Fig'. 3,

The operation and way of using' my iinproved apparatus are as follows: The cover 4 being removed and the bobbin or spool 11, with its paper tube 23, having been brought onto the brake-tube 19 20, the latter is placed on the hollow spindle 3, and at the saine time the loop-shaped spring 21 by pressing the eyelet 22 is opened suffcientl y to enable said spring 21 to embrace the g'roove of the pulley 2O of the brake-tube 19 20, as shown in Fig'. 4. Then the brake-tube 19 2O is removed, the spring 21 occupies the position shown in Fig. 6. The brake-tube 19 2O having been put in place tog'ether with the spool 11, the cover 4 fixed onto the upper part of the box or casing 1, whereupon the pin7 of the spring 5 again engages with the hole 6 of the cover 4. The thread 10 is then passed through the slit 12 of said box or casing 1, through the loop 28, the vertical tube 29, the loop 30, and finally over the little guide-pulley 9, so that the resistance of the air cannot affect the thread 10. The central wire or thread, which is to be pulled gradually in an upward direction, is then passed through the support 17, the hollowspindle 3, and between the smoothing-block 24 and the interior surface of the thread or wire guide 3, whereupon the apparatus is ready for working. Vhen the box or casingl is turned on the support 17 by means o'f the belt or other pulley 13, the thread wound off from the bobbin or spool 11 is gradually wound around the central wire or thread moved in a vertical direction, the smoother 24 25 pressing on the central thread or wire already covered with thread and equalizing the windings, so as to improve the final result obtained. During the normal rotation of the box or casing 1 the brake-spring 21, which is in engagement with the groove of the pulley 20 of the brake-pulley 19 20, is pressed with more or less force against the groove of said pulley 20, owing' to the centripetal force due to the motion of the named pulley 20, whereby the motion of the brakepulley 19 2O is retarded, so as to prevent the thread 10 from being unwound too quickly or sl'iontaneously from the bobbin or spool 11. Then the box or casing 1 is at rest or moves slowly, the brake-spring 21 does not press against the grooved disk or pulley 20, but only when the speed is sufficiently increased, in which case it exercises a retarding action on the brake-tube varying in direct proportion with the velocity.

Of course I do not limit my invention to the special form of apparatus shown in the drawings, as it can be carried out in practice in various ways.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is"
